Abstract:
One embodiment of the present invention provides a system for controlling operations of a power amplifier in a wireless transmitter. During operation, the system receives a baseband signal to be transmitted, and dynamically switches an operation mode of the power amplifier between a high power back-off mode having a first power back-off factor and a normal mode having a second power back-off factor based on a level of the baseband signal.
